CYLINDER-WELDING APIARATUS.

Specification of Letters Patent.

Patented June 27, 1916.

Be it known that I. PHILIP GoLonBscli, a subject of the Emperor of Germany, residing in Hoboken. county of Hudson, State of New Jersey. have invented certain new and useful Improvements in C vlinder-llelding Apparatus. of which the following is a specification.

This invention is designed to lap-weld long pieces of pipe.

It comprises a support upon which the material composing thepipe, cylindrically formed. is held throughout its length. and it is provided with a plurality of curved beds for dili'erent sizes of pipes; a carriage on which the pipe support is held; means for vertically adjusting the support and means for locking the support with any one of its curved s in uppermost osition. A mandrel is provided suppo by one end on a suitable frame so as to extend over the pipe bed inside the pipe. said mandrel harinal an adjustable anvil at its free end controlled by a hydraulic cylinder and piston at the fixed end of the mandrel. The welding is produced by a roller, shaped to act on the outside of the pipe. located directly over the anvil and adapted to be reciprocate-d lengthwise of the pipe and pressed against the pipe by a hydraulic controller. These devices with other features of construction will, by reference to the accompanying drawings, now be described.

Figure l is a side elevation. partly in section. of a pipe welding machine embodying the features of this invention. Fig. 2 is an end view of the same, looking toward the right. Fig. 3 is a vertical section on the line 3, 3. Fig. 1. Fig. 4 is an enlarged sectional view of the welding roller, the anvil and the pipe support taken on line 4, 4, Fig. l. and: Fig. 5 is a longitudinal section, on an enlarged scale. of the outer free end of the mandrel and the adjustable anvil.

The pipe support- 6 is equal in length to. or somewhat in excess of, the longest pipe the machine is adapted to weld. It has a series of grooves of dilerent curvatures formed in it throughout its length, constitut-ing beds for pipes of dilierent sizes. and is provided 'with trunnions 8 at its ends seated in vertically movable blocks 9. These blocks are fitted to slide in end frames 10 of the carriage. As many pipe beds 7 as the cross section of the support 6 will admit of may be provided, four being shown in the drawings.

Theend frames 10 of the carriage are connected together at their lower parts by girders 11 and at their u per parts b v tie rods and spacing lengths o pipe 1:2., each end frame being provided with a pair of wheels 13 that run on tracks 14 located at the sides of a plt 15, into which the lower ends of the frames 10 extend. The tracks 14 are sailiiently long to admit of the pipe support bemg moved beyond the mandrel and anvil and entirely1 over the same. Means are provided or moving the carriage, consisting of a motor 16 and a drum 17, driven thereby. which controls a rope or chain 18 passing over guide sheaves 19 located at the ends of the pit 15, said rope or chain being connected by its ends to te frames of the carriage through the medium of suitable yokes 20.

The pipe support holding blocks 9 are vertically adjusted by screws 21 which are raised and lowered b v ratchet wheels 22 set in openings in the end frames 10 of the carriage and actuated by suitable means. Pieces 23 are adjusted to pass through lues on the blocks 9, and are sized to lit snu y into holes or grooves 24 in the trunnions 8,` of the pipe support 6., arranged so that the bed 7 in use will be held in proper relation to the other parts of the machine.

The mandrel 25 is rigidly connected at one end to the end piece 26 of the main frame of the machine and extends under the other end piece 27, said end pieces of the. frame being suitably constructed and joined together at their upper ends by longitudinal gil-ders 28. This mandrel has a longitudinal bore through which paes a pipe extension 29 of the ram of a hydraulic cylinder 30, connected to the outer side of end piece 26, and to the end of this ram extension 29 is secured a double wedge piece 31 fitted to slide on the inside of the free end of the mandrel 25. This end of the mandrel is provided with a detachable shoe 32 held in a transverse dovetail groove by a wed 33. There is provided a shoe 32 for each size of pi to be welded, formed to fit the interior o the pipe. which rests on the support 6. in the. pipe bed 7 of the same circularity as the exterior of the pipe, as clearly shown in Figs. 4 and 5. 34 indicates the pipe. These views also show an anvil 35 rounded at its upper surface to fit the interior of the pipe to be welded and fitted to slide vertically in the outer part of the mandrel '25. inclined liearings 36 are formed on the anvil adapted to coact with the double wedge piece 31. This arrangement is such that when the wedge piece is withdrawn by the hydraulic controller 30. the anvil end of the mandrel contracted. leaving the pipe free to be moved b v its carriage. away' from the mandrel .so that its seam part ma;`- be heated b i' a suitable furnace. or with the heated part of the pipe set over the anvil for the seam to bc welded by the welding device. now to be dcscribed.

The welding means comprises a roller 3T having a groove shaped to lit over the one side of the pipe to be welded and free to rotate on a short shaft 38 with anti-friction rollers 39 preferably placed in the roller bearing. Shaft 38 is held in the forks 40. of a slide 41, the bearings of the shaft being open downwardlyr to permit of the ready removal of the welding roller and of replacing it by another one having a di'erent shaped groove adapted to fit over and act on a different size pipe. Cotter pins P2 are shown to hold the roller and the shaft in the fork of the slide 4l. A head 43 carried by the ram or piston rod 44 of a vertically arranged hydraulic cylinder 45 has guides on its sides on which the slide 4l. 'hy reacting guide ways, is free to slide in direction paralled to the mandrel and to the pipe 34 held on the pipe bed. It is preferred to emploiY anti-friction rollers 46 between the pressure resisting sur-face of the slide 41 and head 43. 0n the sides of the stem of the head 43 are keys or splines 47 that fit and slide in corresponding grooves formed in the bearing 4S. centrally located in the upper part of the end piece 2 of the main frame. thereby holding the guides of the head on which the slide 41 reciproeates parallel to the axis of tbe mandrel and pipe. The hydraulic c vlinder 45 is supported and held co-axially with the bearing 48 by a cross piece `and standard posts 49.

50 designates a lever having its fulcrum 51 on a standard. projecting from the frame. and with its short end pivoted at 52 to the stern of the head 43. the long end of this lever being provided with a counter-weight 53. whereby the head 43 and Vits attached parts are over-balanced and the welding roller 3T raised away from the pipe 34 when the pressure in the cylinder 45 is released.

The slide 41 may be actuated by any adeqnate means to canse the roller 37 to reciprocate on the part of the seam of the pi located over the anvil A suitable mec :mism for this purpose is a connecting:A rod 54 having one end forked and connected b v studs 55 to the side of the slide 41 and its other end engaged by a, crank 56 carried hy a Shaft 57, a gar wheel 58 on shaft 57 and driven by a motor 59 through the medium of a pinion (l0 on the motor. a gear 61 on :i shaftand a pinion 63 on this shaft meshingr into the gear vvlieel 5S. The motor and gearing are located at the upper part of the end piece 26 of the main frame.

The pipe supporting bed G is. as before described. held with any one of the pipe beds 'i in operative position h v the pieces which pass through lugs on the blocks 9 and enter slots or openings 24 formed in the trunnions 8. lVhen it. is desired to change the pipe bed for a. different size pipe. the pieces 93 are moved down until their ends clear the trunnions. Their downward movement for this purpose is determined by pins which pass through slots 64 formed through the reduced portions of the screws. or pins in said reduced portion acting in slots formed in the sliding blocks 9. Then the blocks 9 are supported by shoulders on the screws then they and the pipe support 6 may be vertically adjusted to bringr the center of the pipe resting on the support in line with the axis of the anvil with the anvil expanded to lit the interior of the pipe: thus a. rigid solid support will be provided for the proper action of the welding roller 37, under pressure due to the h vdaulic controller 45. to pres and roll the seam against the anvil It will be observed that the welding operation is performed by the combined downward pressure of the roller 3T on the seam of the pipe and the longitudinal moi-ement of the roller lengthwise on the seam. and that the pipe firmly supported during this op eration h v the support 7 and b v an anvil which is expanded within the pipe and hears against. the seam and also against the opposite side of the pipe.

I claiml. A pipe welding machine. comprising means for supporting the pipe on its under side. a roller for closing the seam which is forcibly pressed against the seam and is at the same time reciprocated longitudinally thereorer. and a mandrel within the pipe supporting an anvil firmly held between and pressing against the bottom of the pipe and the top thereof.
